岩棉保温材料的绿色生产与应用来源:http://fanmadetrailers.com   时间:2017-11-23
保温材料按照材质组成来划分,大致可以分为两大类:一是有机聚合物绝缘材料,如发泡聚苯乙烯泡沫板、硬质聚氨酯泡沫板等;二是无机保温材料,如岩棉、玻璃棉、泡沫玻璃板等。
Insulation materials can be divided into two categories according to the material composition: one is organic polymer insulation materials, such as foam polystyrene foam board, rigid polyurethane foam board, etc.; two inorganic thermal insulation materials, such as rock wool, glass wool, foam glass board, etc..
其中,以岩棉、玻璃棉为代表的矿物棉因具有其他保温材料所不具有的优点,在保温材料行业内备受推崇,产量一直呈现逐年上升的态势。其中岩棉以其更高的耐火极限和熔点温度,在建筑保防火保温方面更受青睐。
Among them, the rock wool, glass cotton as the representative of the mineral cotton because of other advantages of thermal insulation material, in the heat preservation material industry is highly respected, production has been showing an increasing trend. Among them, rock wool with its higher fire resistance limit and melting point temperature, in the building fire prevention and insulation more favored.
外墙保温岩棉板具有较高的抗压和抗拉伸强度、较低的吸水和吸湿性、尺寸稳定性良好、不会产生热膨胀或收缩、耐老化等优点,能与外墙系统兼容,对建筑物提供有效的保温节能、防火及极端气候保护等多种性能。
The external wall thermal insulation rock wool board has high compressive strength and tensile strength, low water absorption and moisture absorption, good dimensional stability, will not produce thermal expansion or contraction, anti-aging and so on, can be compatible with external systems, to provide effective insulation, fire prevention and energy saving performance of extreme climate protection for buildings.
岩棉带可以作为防火隔离带,与燃烧性能达不到A级的保温材料配套使用,以提高建筑物外墙的消防防火功能。在火灾条件下,防火隔离带既要阻止或减缓火源对直接受火区域内外保温系统的攻击,又要阻止火焰通过外保温系统向外传播。
Rock wool belt can be used as fire isolation belt, and the combustion performance can not reach class a insulation materials supporting, in order to improve the building exterior wall fire prevention and fire protection function. In the fire condition, the fire isolation belt not only prevents or slows down the fire source's attack on the heat insulation system inside and outside the direct fire area, but also prevents the flame from spreading through the external heat preservation system.
